I recently lost the ability to AirPrint on my Ubuntu 12.04 box. I checked, and it was running CUPS 1.5.3, so naturally I wanted to upgrade it to the latest version of cups. I apt-get --purge remove'd it, and I tried to build the CUPS package from source on their site. When I try to start the deaemon with service cups start or /etc/init.d/cupsd start, I get:
Is CUPS 1.7.1 incompatible with Ubuntu 12.04? Just curious, as I'll likely need to reinstall the old version if this is the case...
cupsd: Child exited with status 127
cups: unable to start scheduler.
